and E1/T1 transport

links

ACE-3400 is a multiservice carrier-class gateway, designed for cost-effective backhauling of 2G/3G voice and HSDPA data traffic over multi-generation access networks, such as Ethernet and SDH/SONET.

ACE-3400 uses advanced pseudowire (PW) technology to deliver cellular and legacy traffic services (ATM, TDM) over next-generation PSNs (packet-switched networks), including Layer-2, MPLS and IP.

Typically located at the RNC/BSC site, the unit converts and aggregates traffic using N × E1/T1, STM-1/OC-3c and Gigabit Ethernet interfaces.

ANY-SERVICE-ANY-PORT

The STM-1/OC-3c and Gigabit Ethernet interfaces operate as user or network ports, per user configuration and depending on the required application.

In addition, ATM or TDM traffic received via the E1/T1 ports is converted by ACE-3400 to either ATM (UNI or IMA), CES or SAT over PSNs, depending on the originating traffic type.

ACE-3400 Aggregation Site Gateway

ATM OVER PACKET CAPABILITIES

ACE-3400 allows up to 512 data pseudowire connections to be established over a packet-switched network.

The following encapsulation methods are supported according to RFC 4717:

• 1-to-1 VC/VP – Each VCC/VPC is mapped to a single pseudowire connection

• N-to-1 VC/VP – Several VCs or VPs can be encapsulated to a single pseudowire connection.

ACE-3400 allows single or multiple ATM cells to be encapsulated per frame.

Over L2 and L3 networks, ACE-3400 uses various encapsulation types: VLANs (virtual LANs), dynamic and static MPLS label assignment, and MPLS in IP.

TDM OVER PACKET CAPABILITIES

By allowing its E1/T1 interfaces to work in TDM mode (user-selectable), ACE-3400 allows 2G cellular traffic to be transported over PSNs.

Both structure-agnostic and structure-aware modes are supported, with up to 8 bundles per E1/T1 port or 128/300 bundles in total.

To compensate for the jitter caused by the packet-switched network, each TDM stream has a jitter buffer of up to 32 milliseconds.

The encapsulation of TDM traffic complies with the RFC 4553 and RFC 5086 requirements.

USING THE LABEL DISTRIBUTION PROTOCOL (LDP)

ACE-3400 uses the MPLS label distribution protocol (LDP) to automatically assign and distribute pseudowires and tunnel labels between MPLS peers.

Note: The LDP functionality requires a software

license. For more information, refer to the Ordering

section.

ATM SWITCHING AND POLICING CAPABILITIES

ACE-3400 provides full ATM switching capabilities, including scheduling and shaping of ATM-based traffic.

Operators can assign each virtual connection (VC) or virtual path (VP) to a service class, define the QoS parameters and shape the ATM egress traffic. ATM traffic policing allows operators to discard, tag or count non-conformant cells per configuration.

ACE-3400 allows establishing up to 1024 VP and VC connections with full UNI/NNI VPI and VCI ranges.

ACE-3400 supports inverse multiplexing over ATM (IMA) versions 1.0 and 1.1, allowing users to define up to 32 or 63 IMA groups.

Each of the unit's E1/T1 ports can be configured to work in ATM IMA, ATM UNI or TDM over ATM mode (structured/ unstructured CES). The fiber optic STM-1/OC-3c interfaces operate in ATM UNI mode.

QUALITY OF SERVICE (QOS) OVER PSN

Over packet-switched networks, QoS is provided according to the network type:

• Layer-2 network – outgoing pseudowire packets are assigned a dedicated VLAN ID according to 802.1Q and marked for priority using 802.1p bits

• MPLS network – outgoing pseudowire packets are assigned to a specific MPLS tunnel and marked for priority using EXP bits

• IP network – outgoing pseudowire packets are marked for priority using ToS or DSCP bits.

Data Sheet

CLOCK SYNCHRONIZATION

ACE-3400 provides robust clock synchronization and flexible timing modes, including:

• Interface-based synchronization – the clock is recovered from the RX traffic of a selected interface, in accordance with G.823 and depending on the network's SLA

• Unicast clock distribution – the master clock is distributed with a dedicated stream towards up to 256 remote PSN peers

• Multicast clock distribution – the master clock is distributed towards the PSN using a single IP multicast clock stream (IGMPv2 host).

GENERIC ROUTING ENCAPSULATION (GRE)

ACE-3400 encapsulates MPLS packets over GRE to establish point-to-point tunnel connection over an IP network. This tunneling service is used to transfer MPLS packets over an IP network without using the IP addressing scheme.

E1/T1 INTERFACES

ACE-3400 includes 32 or 63 (as ordered) E1 or T1 multiservice ports that can be configured to work in ATM UNI/IMA or TDM mode, per user configuration.

This Any-Service-Any-Port framework enables high flexibility in deployment within various backhaul solutions.

Optional patch panel adapters can be used to convert the E1/T1 ports terminated in six 64-pin Telco connectors. Each Telco connector supports up to 14 E1/T1 ports.

INTERFACE MODULES

The ACE-3400 chassis provides slots for installing up to four hot-swappable interface modules in total. An interface module's type can be either SDH/SONET or Gigabit Ethernet.

SDH/SONET INTERFACES

ACE-3400 supports up to three STM-1/OC-3c UNI interfaces, or up to two channelized STM-1/OC-3 interfaces:

• The STM-1/OC-3c UNI interfaces map physical layer and ATM cells into STM-1/OC-3c (ATM-155) according to ITU I.432

• The channelized STM-1/OC-3 interface provides up to 63 VC-12 or 84 VT1.5 channels. Each channel can be set to ATM UNI/IMA or TDM mode.

Two SDH/SONET ports of the same type can be configured to work in automatic protection switching (APS) mode, to provide 1+1 protection according to G.841 Annex B.

GIGABIT ETHERNET INTERFACES

ACE-3400 supports up to two Gigabit Ethernet ports, used for pseudowire (PW) connectivity, user connections and inband management access over a single link.

To allow reliable and uninterrupted service over packet-switched networks, two Gigabit Ethernet interfaces can be set to work in the 1:1 or 1+1 automatic protection switching modes, according to IEEE 802.3ad.

MAIN MODULES

The main modules of ACE-3400 affect the nature and overall functionality of the unit. Three distinct functionality types are available:

• Delivering ATM traffic over fiber optic STM-1/OC-3c links and packet-switched networks

• Aggregating VC-12/VT1.5 circuits over channelized STM-1/OC-3 or GbE links

• Aggregating E1/T1 traffic (ATM UNI/IMA or TDM) over STM-1/OC-3c or GbE links.

Accordingly, the main modules can be replaced in order to fulfill different backhauling tasks.

SYSTEM REDUNDANCY

ACE-3400 allows two identical main modules to work in redundancy mode, which protects the unit's data matrix and main CPU in cases of unexpected module reset. One main module is set as the active module, while the second is in standby mode, ready to work in place of the active one at any moment.

OAM AND DIAGNOSTICS

Comprehensive monitoring and diagnostic capabilities include:

• Pseudowire connectivity check

• External and internal physical loopbacks on STM-1/OC-3c/OC-3 ports

• Cell test towards the ATM connections.

ACE-3400 periodically verifies the connectivity status of pseudowire connections, using VCCV-BFD messages according to the 'draft-ietf-bfd-base' requirements. If a failure is detected, a notification is sent to both the remote peer and the ATM/TDM connection of the specific PW. This allows complete monitoring over the pseudowire connections in real-time.

ATM/TDM and PSN port alarms are propagated over the packet-switched network from end to end. This includes the mapping of:

• Packet-switched network alarms to ATM alarms

• ATM/TDM alarms over the PSN to the remote customer equipment (CE)

• Physical failures of ATM/TDM ports, over the packet-switched network towards both the local and remote CE.

For conventional ATM cross-connects (XCs), OAM is supported according to ITU I.610 requirements:

• F4 and F5 OAM

• Configurable OAM mode per connection point

• Segment/intermediate mode for user connections and end-to-end mode for the management connection

• AIS and RDI cell detection and generation upon physical layer and ATM layer failures

• CC cell generation and LOC state detection per VP/VC

• Loopback location ID and configurable loopback source ID per device.

Performance monitoring is provided by Ethernet and IP-layer network condition statistics, such as packet sequence errors (loss or misorder) and packet delay variation (jitter), which are monitored and stored by the device.

ACE-3400 collects statistics per physical port and per connection for 15-minute intervals. Statistics for the last 6 hours are stored in the device and can be retrieved at the network management station.

For diagnostics purposes, ACE-3400 maintains a cyclic event log file that stores up to 4096 time-stamped events. In addition, an internal system log agent can send all reported events to a centralized repository or remote server.

MANAGEMENT

ACE-3400 can be managed using different access methods, via:

• A dedicated RS-232 or 10/100BaseT port

• Dedicated VC defined on any ATM port

• Gigabit Ethernet uplink port, using IP-based connection (raw IP or over PW).

Software upgrades and configuration files can be downloaded/uploaded to/from ACE-3400 via TFTP or XMODEM.

The following applications can be used for management:

• Menu-driven terminal utility via an ASCII terminal connection

• Telnet via an IP-based connection

• Secure Shell (SSH) via any secure client/server application

• ConfiguRAD, Web-based element management tool via an IP-based connection

• RADview-EMS, RAD’s CORBA-based element management access system.

The unit can be managed by and report to up to 16 different users simultaneously. Accounts of existing and new users can be defined/changed remotely, using a dedicated RADIUS server.

ACE-3400 allows retrieval of the current date and time from a centralized location, by synchronizing with an SNTP (System Network Timing Protocol) server.

ADVANCED SECURITY FEATURES

ACE-3400 supports the Secure Socket Layer (SSL) protocol for enabling secure Web access to the unit. If enabled, the SSL protocol encrypts the data between the TCP and HTTP Web layers.

Telnet-like management can be secured using a Secure Shell (SSH) client/server program. Instead of sending plain-text ASCII-based commands and login requests over the network, SSH provides a secure communication channel.

In addition, ACE-3400 supports SNMP version 3, providing secure access to the device by authenticating and encrypting packets transmitted over the network.

MODULAR ARCHITECTURE

The modular architecture of ACE-3400 allows hot-swappable modules to be replaced in the field while maintaining uninterrupted service. The unit is fully accessible from the front panel.

The unit's full hardware redundancy features (fans, power supplies, modules) ensure a fail-safe, continuous operation, making ACE-3400 ideal for carriers and service providers.
